Analysis On The Internal Structure Of Wind Turbine Tower

Qingdao Wuxiao | Updated: Oct 19, 2017

The cabin is equipped with key equipment for wind turbines, including gearboxes and generators. The maintenance staff can enter the cabin through the wind turbine tower. The left side of the cabin is the wind turbine rotor, rotor blades and shaft. Rotor blades: catch the wind and send the wind to the rotor shaft.Wind Turbine Tower 

Modern 600 kilowatts of wind turbines, each rotor blade measuring length of about 20 meters, and was designed like a wing of the aircraft. Axis: The rotor axis is attached to the low speed shaft of the wind turbine. Low speed shaft: The low speed shaft of the wind turbine connects the rotor shaft to the gearbox.Wind Turbine Tower

In the modern 600-kilowatt wind turbines, the rotor speed is quite slow, about 19 to 30 revolutions per minute. The shaft has a conduit for the hydraulic system to activate the operation of the aerodynamic brake. Gearbox: The left side of the gearbox is a low speed shaft, which can increase the speed of the high speed shaft to 50 times the speed of the low speed shaft. High speed shaft and its mechanical gates: High speed shafts run at 1500 rpm and drive generators. It is equipped with emergency mechanical gates for use when the aerodynamic brake fails or when the wind turbine is repaired.Wind Turbine Tower

Electronic controller: Contains a computer that continuously monitors the state of the wind turbine and controls the yaw. To prevent any failure (ie, overheating of the gearbox or generator), the controller can automatically stop the rotation of the wind turbine and call the wind turbine operator via a telephone modem. Hydraulic system: Used to reset the aerodynamic gates of wind turbines. Cooling element: Contains a fan for cooling the generator. In addition, it contains an oil cooling element for cooling the oil in the gearbox. Some wind turbines have water-cooled generators.Wind Turbine Tower
